Specification of Application filed ages a,

T 0 all whom it may concern.

Be it known that I, JOHN A. BEN'IZ, a citizen of the United States, residing at Harris-- burg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Lugs; and I useful improvements in traction lugs of the detachable type, and its object is to provide a crown lug which is adapted to be secured to and over a highway cleat which is bolted or otherwise secured to the wheel of the tractor or other vehicle.

Another object of my invention is to provide a lug which may be removably secured in position by a single bolt, thusmaking the operation of attaching and detaching the lug, quite simple.

btill another object of my invention is to provide a. tractor wheel with a set of high way cleats permanently secured thereto, and a set of crown lugs which are adapted to be applied to and removed from said cleats, thus producing a change of traction surface very readily, and while it gives the user two complete sets of cleats, it is only necessary for him to handle one outfit, as the highway cleats are never removed, except for re part of the tractor wheel;

With the above and other objects in view which willappear as the description proceeds, the invention consists in the novel featuresherein set forth, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings, 7

ig. '6, is a sectional view taken on line I6-6: of Fig. 5,'and Y 1 F 1g. '7 is a sectional view taken .on line =-7 of Fig. 5. 7 In the drawings like numerals designate the same parts throughout the several views. 1 designates the rim of an ordinarytractor wheel, 2, is a highway cleat, which is preferably made of cast metal and is adapted to be secured to the tractor wheel by means of the bolts and nuts 4, which engage the cleats at the recesses 3 and pass through the open in s 3. I

hese cleats are placed onthe wheel preffl erably in diagonal position and the ends are formed parallel with the edge of the wheel. At one end of each cleat there is provided a recess 5,'adapted to engage the rib portion 7 of the crown lug 6. Theother endis provided with a slotted ear10,formed with a recessed portion 11 to receive the bolt-'9.

The crown lug 6 is made of similar material to that of the cleat 2 and is formed wedge-shape in cross section and'isrecessed on its under side to fit over the highway cleat2.

At one end of this lug there is provided a rib portion? which extends across the en tire width of the lug and engages the recess 5 in the cleat 2, and secures theend of the lug in place. At the "other end of the lug is a recess 8 adapted to receive the head of the bolt 9 which passes through the lug and v cleat, and secures the two together. I

Under ordinary circumstances and for use on the road, the hi hway cleat 2 is all that is necessary, but w en the tractor is to be used on soft ground and when greater trac-'- tion is needed, the crown lug is put in placeby first inserting the rib 7 in therecess 5 of the cleat, and then lowering the other end of the lug so that the recess 8 coincides with the recess 11 in the ear 10. The bolt 9 is then inserted through the two recesses 8 and 11 and a nutand lock washer placed thereon which are housed by the recess 11. i

From the foregoing, I believe that the con-1 struction, operation and advantagesof my invent-ion may be clearly understood with- V out further description and in' conclusion I may state that the details of construction may be modified considerably without departing from the spirit of the invention as set forth'in the following claims.

What I claim and desire to secure by Letters Patent is 1 l. The combination with a tractor wheel, of a: cleat secured thereto, a supplementary traction lug adapted to fit over said cleat and 7 means provided at the ends of said cleat, in

dependent of the Wheel rim for removably securing said supplementary lug to the cleat.

2. The combination with a tractor wheel,

"of a cleat secured thereto,a crown lug adapted to fit over said clcat and means for se-V curing said crown lug to the cleat, said means consisting of a rib and recess engaging one another, at one end of the demos and a bolt and nut construction at the other end thereof;
